CHECK-ROWER AND DRILL FO'R CORN-PLANTERS.

SPECIFICATION forming part of Letters Patent No. 272,855, dated February 27, 1883.. Application filed May 22, 1882. (No model.)

To all whom it may concern:

Beit known that I, BENJAMIN FRANKLiN CHRIST, a citizen of the United States, residing at Peabody, in the county ot Marion and State ot' Kansas, have invented anew and useful Improvement in Check-Row Attachments for Corn-Planters, of which the following is a specitication.

My invention has relation to the class of seeders and planters, particularly to corn-planters, or those machines wherein the seed is dropped only at certain intervals and not continuously; and my said invention consists in a novel construction and arrangement of mechanism whereby the seed-dropping slide is operated by direct and positive action from the groundaXle of the machine. Acorn-planter supplied with my check-row attachment is therefore automatic in its entire operation, and the necessity of an attendant riding upon the machine to operate the seed-dropping slide by hand, or the employment of a knotted cord stretched across the field by which to operate the seedslide as the machine passes over said cord, is dispensed with.

Referring to the drawings forming part of this specication, Figure l will be found to represent a perspective view of my check-row attachment for corri-planters; Fig. 2, a detached view of the slotted yoke bywhich connection is made between the seed-dropping slide and my apparatus; Figs. 3 and 4., views ofthe cog- Wheels employed in my apparatus to drive the same, the 011e in Figa being attached to the driving-axle of the machine and meshing with and by this means imparting motion to the one shown in Fig. 3. Figs. 5 and 6 represent a side elevation and plan, respectively, ofthe device as applied to a seed-planter frame.

In carryingout my invention I proceed about as follows: To the ground or driving wheel W of any ordinary corn-planter is first secured a l suitable gear-wheel, L, Figs. 4 and 5, which t I IO furnishes the motive power for my apparatus, which apparatus consists of the following parts: To a bed or support, A, is attached, at one end, a transversely-placedframe or stand, F, and at the other end a longitudinally-placed stand, H. These stands F H carry axle-boxes O 0 and O' O, respectively, in which shafts E and G revolve and tnd their bearings. To the end of the short axle E, in bearings 0 O, is

secured a cog-wheel, K, which meshes with the cog L on the ground-wheel W of the machine, and through which motion is imparted to the entire apparatus. This wheel K is provided with a grooved hub, as shown in Fig. 3, into which groove a lever is arranged to operate to move the said wheel backward or forward upon the shaft E to throw the said Wheel in or out ofgear with the wheel Lon the groundwheel of the machine, the axle E having a long slot therein, into which the wheel K is keyed and so arranged in the usual manner as to permit this movement. Secured to and projecting in opposite directions from the short axle E are two arms, S S. To the inner end of the axle, G is secured a curved or semicircnlar piece, R, and to the outer end the crank-arm I, by which the seed-droppingslide is operated, is adjustably secured. The frame H is made adjustable by slot and set-screw T in its base.

N is a hand-lever, pivoted to arm or brace C from the support- F, the end D of which lever engages in the groove in the hub of the cogwheel K, and which forms the means by which said wheel is adjusted.

As will be seen, provision is made at the outer endot' the shaft or bar G by which the adj nstment of the crank-arm I may be effected t0 permit the apparatus t0 be used on differentsized machines.

U, Fig. 2, is a slotted angle-iron, secured to the seed-slide V, which forms the connection between the crank-arm I and the seed slide.

The entire apparatus is secured, as shown in Figs. 5 and 6, to the side rail, P, ot' the planterframe by yokes or brackets J, or by any other suitable means.

The operation of the parts is about as follows: Motion being imparted to the wheel K through the wheel L, attached to the drive.- Wheel of the seed-planter, the short axle E is caused to revolve, which brings the arms S S alternately in contact with one side or the other of the curved piece R. This causes the shaft G to make a half or partial revolution, and through the crank-arm I moves the seeddropping slide backward and forward.

By means of the lever N the parts may be instantly thrown in oroutof gear and the operationot' the seed-dropping machinery stopped. By reason of the adjustability of the crankarm the apparatus may be applied to different- IOC pensed with.

sized machines, and by moving the frame H to or from the frame F a long* or short stroke is obtained, because ofthe arms S S acting to a greater or less extent upon the semicircle R.

By the construction and arrangement of parts herein shown and described,a simpleand effective means is provided for operating the seed-dropping slide of a corn-planter, and one that Will be positive and certain in its movement. The uncertainty and trouble of hand operation is therefore overcome and the trouble incident to tbe use of knotted cords dis- B v using different-sized Wheels K, the intervals 0f planting or of the operation of the seed-dropping slide is effected to any extent desired. I

Having thus described my invention, its op- I 2. The combination, in a check-rower, of z5 frame F 0, carrying short axle E, with arms S S,and wheel K, leverN. adjustable frame H O', carrying-axle G, with curved end R. and crankarm I and gear-wheel L on the drive-shaft of the planter, as hereinbeore described, for the 3o purposes specified.
